It's a 12 mile casual bike ride that will start at Cobble Hill Park and then pass through the Columbia Waterfront District, Red Hook, Park Slope, Prospect Park, Gowanus and loop back to Cobble Hill.

There will be several scenic rest stops as the ride follows mostly calm streets with some light vehicular traffic. Several Bike Marshals will travel alongside the group, guiding the ride. (Bike Marshals will also be prepared to handle any urgent bike repairs needed.)

Light snacks and water will be provided but riders should be prepared with sunblock, plenty of water, and ready for a light pace that will include some cobblestone streets (bumpity bump) in Red Hook and the 9th Street hill in Park Slope, with an option to also ride the hill within Prospect Park's car-free loop.
